Okay, here's what I propose; write up as much as you feel you can and then send the result to BC and me. We'll treat it like any other sheet but in the early IC posts, we'll mention that your Primarch is engaged in a campaign on the far side of the galaxy and so will not be present for the events of the first real life few weeks of the IC, which is a bummer but at least you'll be established as part of the universe. When you have free time again, you can tell us and your Primarch can turn up having successfully (or unsuccessfully) dealt with whatever held them and can join the action.

The alternative is that you simply wait the two weeks before joining but that will probably require much more retconning to make your character a part of the group.

What do you think?
